I highly, highly doubt Verizon will start selling LTE-only phones until their LTE network has expanded to cover the same areas as their CDMA network. They'd lose millions of subscribers.
I am looking forward to LTE eventually though, since then Verizon and AT&T will be using the same wireless technology. Competing standards just make things unnecessarily complicated.
In my dreams, I also imagine a less subsidy/contract/nickel-and-dime-driven mobile marketplace, where compatible, open networks compete for business by driving the costs of data access downwards (since all traffic is data, really) and removing complicated "minutes/texts/data" plans from the picture... But those are just dreams. 😉
